Executive producer of The Big Bang Theory just announced at the San Diego Comic-Con that in Season 10, we will finally be meeting Penny’s mum, “We are finally going to meet more of Penny’s family. We are going to meet Penny’s mom and her brother in the first episode back. We are super excited that Katey Sagal will be playing Penny’s mom… We’re really excited about Katey joining us and becoming part of our little family.”
Katey Sagal played Kaley Cuoco’s on screen mother in the ABC comedy 8 Simple Rules and to bring them back together is just screen perfection. Molaro also revealed that Jack McBrayer of “30 Rock” will play Penny’s Brother. The show will return to CBS on September 19th.
